I don't remember the answer, but I didn't get it right. I figured it out later, and emailed the answer to the hiring manager.

Using the dice you can count to a maximum of 66 combined. When the plane flies by on the 1st month's 30th day, each day after that at the same approximate time in the day you can increase the value of the dice by 1. For example plain flies by on 30th day of 1st month. the next day you wake up and assuming plane flew by at dawn you place the side with the 1 facing up. Each dawn after that you increase to 2, 3, 4, 5, 6-- after six you would use both die, and make some indication to your self saying that 1+6= 7, 2+6=8... and so on after you reach the 4+6=10th day it would be easier to use the die to show "1""1"-> 11th day, etc. That way eventually, you can make a calendar that tells you the day of the month.

Using two digits in "base 6" you can count up to 35. Typically base 6 would use digits 0 to 5, but in this case you can adjust and use 1 through 6.

@Rikesh: How will you indicate 17, 18, 19, 20, 27, 28, 29, 30.Here is what i think...D D6*0+1=16*0+2=26*0+3=3..6*0+6=66*1+1=76*1+2=8..6*1+6=126*2+1=136*2+2=14..6*2+6=186*3+1=196*3+2=20

Basically 2 dice has 6 sides so forDice 1: mark 0 1 2 4 6 8Dice 2: mark 1 2 3 5 7 9And those two can make up all days of the monthOr you can map 1-6 with those numbers for each dice

Rikesh's answer is not correct. cuz 1+6= 7. But with his implementation, you would use 1, 6 to represent 16th also. You can argue that you could use 6,1 to represent the 16th. However, I think MS wants the more "geek" way of the solution, which is one I upvoted the base 6 solution.

How about...Dice 1: each pip equals 1 day: 1 pip =1 day, 2 pips = 2 days, etc.Dice 2 each pip equals 5 days: 1 pip = 5 days, 2 pips = 10 days 3 pips = 15 days etc.Die 2 is always to the left of Die 1.For days less than or equal to 5 use 1 die.When counting a day that is a multiple of 5 (days 5,10,15 etc.) count day by putting Die to 5 pips and Die 2 to the remaining number of days.
